Abstract

Millets hold an immense assurance for food safety and nourishment amid ever-rising agricultural expenses and climate alterations. They are healthful, have supplementary wellbeing profit and need remarkably fewer effort overheads for crop growing. These characters draw attention to millets as a plant of preference for the humankind in the course of emergent alarm about environmental changes. Millets have the prospect to provide biomass and thus bioenergy, reduced carbon emission, carbon footprint and sustainable modern agriculture. As the rate of expansion in budding countries is increasing day by day, the scarcity of energy is a big panic and there is a… More >

Abstract Halophytes are an excellent choice for the study of genes conferring salt tolerance to salt-sensitive plants and, they are suitable for reclamation and remediation of saline soil. We develop an in vitro plant propagation protocol and studies of genes involved with GB and Pro biosynthesis in Suaeda edulis. Axillary buds were used as explants and cultured in different treatments on Murashige and Skoog (MS) medium supplemented with different concentrations and combinations of plant growth regulators. The highest number of multiple shoots was on MS medium containing 1 mg/L Benzyladenine (BA) and / or 2 g/L activated carbon with 5.5 ±… More >

Abstract The endoplasmic reticulum (ER) is an organelle in the cell where proteins are created and folded. Folding is a very elaborate process that is often interrupted by various biotic and abiotic stresses, leading to the formation of unfolded and misfolded proteins called ER stress. Dithiothreitol (DTT)-induced unfolded protein response (UPR) in endoplasmic reticulum (ER) has been recently reported in plants. Also, previous studies demonstrated that treatment with polyethylene glycol (PEG₆₀₀₀) could stimulate water deficit in crops. However, further researches should be conducted to elucidate the molecular mechanism of ER stress response and the relationship between water deficiency and ER. In… More >

Abstract Salt stress is one of the major abiotic stress in plants. However, traditional approaches are not always efficient in conferring salt tolerance. Experiments were conducted to understand the role of Trichoderma spp. (T. harzianum and T. viride) in growth, chlorophyll (Chl) synthesis, and proline accumulation of C. pepo exposed to salinity stress. There were three salt stress (50, 100, and 150 mM NaCl) lavels and three different Trichoderma inoculation viz. T. harzianum, T. viride, and T. harzianum + T. viride. Salt stress significantly declined the growth in terms of the shoot and root lengths; however, it was improved by the… More >

Abstract Increased urbanization and industrialization have greatly contributed to the emission of higher amount of heavy metals such as cadmium, nickel, and lead into the environment. These metals are non-biodegradable and toxic, causing much effects on plants and by extension to animals and humans, which have become a major global concern. The inherent ability of plants to resist heavy metal toxicity seems to be the most sustainable and cost-effective strategy. Castor plant is widely studied due to its tolerance to the effects of heavy metal contaminated soils, owing to its large biomass content and high accumulating capacity. Castor plants to some… More >

Abstract The heavy metals present in the environment accumulate in the plants and affect their productivity and yield. By entering the food chain, metals cause several serious health problems in human beings as well as in other organisms. Indole acetic acid (IAA) is known to act as a signaling molecule between symbiotic association of metal accumulating plants and plant growth promoting rhizobacteria (PGPR). Present study demonstrated a protective role of IAA against surplus Zinc (Zn)-induced toxicity to Hordeum vulgare seedlings. Elevated Zn concentrations suppressed the plant growth, caused a reduction in leaf relative water contents (RWC) and elevated free proline and… More >

Abstract The aim of the study was to investigate some physiological effects of an insecticide (Akira 20-SP) with acetamiprid agent on Cin misir Adapop 10 and Sert misir Adapop 2 cultivars of corn plants in different concentrations [0 g/L, 0.6 g/L (recommended concentration), 1.2 g/L]. Photosynthetic pigment substances, total soluble protein and proline contents were determined. Analysis of treated leaves showed that the recommended concentration resulted in higher chlorophyll value in Cin misir Adapop 10 and Sert misir Adapop 2. Carotenoid amounts increased in Cin misir Adapop 10 and decreased in Sert misir Adapop 2 to the control. Total protein contents… More >

Abstract Pecan [Carya illinoensis (Wanngenh) K. Koch] is one of the most important nut crops in arid and semiarid regions of Mexico. Here, most pecans are grown in saline soils having poor permeability which are further degraded by the use of low-quality irrigation water. Salinity adversely affects both pecan nut quality and yield. Little work has been done to explore the physiological effects of salinity on native pecan trees. Here we examine physiological changes determined by exposure of pecan seedlings to sodium sulfate (Na₂SO₄) at four concentrations: 1000, 2000, 3000 and 4000 mg/L applied twice weekly over a 70 d period.… More >

Abstract Four dynamic conditions to evaluate the effects of stress on production of biomass, essential oils, Thymol, carvacrol and proline accumulation in Lippia graveolens H.B.K. were investigated under greenhouse conditions. A bifactorial design assessed four environmental conditions (factor B): commercial nutritive solution (B0); Water (B1); moderate stress (B2), and intermediate (B3) stress nested under (Factor A) salinity (NaCl) and ion concentration (Cu²⁺) and (Fe²⁺) stresses. Average production of fresh weight and number of leaves were reduced under NaCl and both ion concentration conditions. However, there were no significant differences on average for the four environments. The amounts of essential oils were… More >

Abstract The objective of this work was to determine the effect of deficiency versus toxicity of N on biosynthesis of proline in fruits of green bean plants (Phaseolus vulgaris L. cv. Strike). Nitrogen was applied to the nutritive solution in the form of NH₄NO₃ at 1.5 mM (N1), 3.0 mM (N2), 6.0 mM (N3, optimal level), 12.0 mM (N4), 18.0 mM (N5), and 24.0 mM (N6). Nitrogen deficiency (N1 and N2) was characterized by having lower proline accumulation in pods and seeds, mainly because proline degradation was stimulated by the enzyme proline dehydrogenase. On the other hand, N toxicity (N4, N5,… More >
